Abstract: This article is based on the background of Jiaxing City's preliminary completion of institutional reform and revision of earthquake emergency plans. It deeply analyzes the current situation of earthquake emergency work faced by Jiaxing City, and proposes a strategic path for building and improving the earthquake emergency system in Jiaxing City from eight aspects: reconstructing and strengthening collaborative emergency systems, improving emergency plans, and guiding social participation. The goal is to enhance the emergency response capacity of Jiaxing City in response to sudden earthquake events, while also hoping to provide valuable reference and inspiration for other cities in the Yangtze River Delta region with similar geographical and socio-economic characteristics in the construction of earthquake emergency systems.
